RecruitingDiagnostic testDetermining Which Regions of the Brain Are Active During Flight Simulation at Separate Timepoints During TrainingThe overall objective is to identify the cognitive circuits associated with military aviator performance by analyzing what anatomic regions of the brain are functionally "active" (neuronal circuit) while being performing virtual flight simulations, the Precision Instrument Control Task (PICT). The flight simulation test will be conducted at two separate timepoints while the subject is receiving a Functional Magnetic Resonance Imaging (fMRI) scan to evaluate which anatomic and functional brain function is associated with precise performance. By scanning at multiple time points we aim to quantify changes in functional and anatomic connectivity that occur throughout the course of training.
